Steganography is a branch of information hiding method to hide secret data in the media such as audio, images, videos, etc. The use of images is very common in the world of electronic communication. In this paper, the parameters that are important in steganography images, have been studied and analyzed. Steganography purposes of security, robustness and capacity of which three are located at three vertices of a triangle, each note entail ignoring others. The main parameters of the methods steganography they've Security, Capacity, Psnr, Mse, Ber, Ssim are the results of the implementation show, steganography methods that these parameters provide have mentioned goals than other methods have improved.
